About this 0.52ct lab-grown oval diamond

This 0.52ct lab-grown oval sits in the half to three-quarter carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG407941470 or 407941470. Listed at 4 retailers as of October 25, 2026, with prices from £229 to £924, a £695 spread on the same certified stone. MOH London lists it at £924. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
